Recently, I was throwing a pot on the wheel and really messed up the top. I chopped the top off and shaped the clay that was left into a rather average small bowl. I started playing with the rim of the pot and hit upon this wavy edge which I thought had some potential. So, rather than recycle it into useable clay again, I decided to fire it.
I was rather pleased with the result and decided to do the same again - intentionally this time!!
